Thanks to a friend, I now have a lovely little aloe plant sitting on my nightstand. Why? Well, not only do aloe plants make great gifts, but they are one of many houseplants that actually purify the air around them. The effectiveness of houseplants in removing toxins from the air was actually part of a large NASA study...more houseplant info here. Aloe takes it one step further and absorbs carbon monoxide overnight, helping you to sleep better. Maybe it's just the placebo effect, but I've been sleeping great lately!
